Abstract

To explore the percolation regulation and inducement of waste fine particles in ore drawing by the block caving method, a simulation is undertaken by using discrete element method software EDEM. This simulation contains coarse-to-fine particle amount ratio, diameter ratio and moisture content, and s...
